This invention relates to a. closure for a water or icebag which iseffected by constricting the neck of the bag by rolling or foldingrolled or the folds.

An object of the invention is 'to provide compressing `means for v'thefolds whereby 'they are constricted and drawn one against the other bythereof.

A further object of the invention is to provide separate elasticclamping tabs for each the clamping' tabs having acommon fastening platewith which they cooperate to compress the folds by tension applied attension applied at the ends :the ends of the folds.

yihe invention consists in the features and the combination andarrangement of parts 29 hereinafter described and particularly point edout in the claims.

in the accompanying drawings the rubber water bag l is provided with anelongated attened neck' 2 of substantial width for receiving either iceor water. The thicknessof the wall of the neck 2 varies in itslongitudinal cross-section and is provided with thinned sections 3 and4:, to establish predetermined lines of folding and facilitate thefolding of the neck. rEhe thick portions are formed by vulcanizing'crossbands of elastic material integral with the neck, the thinned portionsit over upon itself and holding it inv folded condition by compressing vthe edges of the flattened portions. The tabs 'being the wall of theneck 4between the thick portions. The thinned section 4 is of greaterarea than the thinned section 3. At the base of the neck 2 a pair ofelastic tabs 5 of rubber 'are connected to opposite sides thereof at areprovided with openings 6 to-engage buttons 7 on a metal plate orstiifening member 8 and the tabs are provided with'openings 9 tocooperate with the key'portions l() on the ends o the plate 8.

The stiff plate 8 is adapted to be securely held in place a ainst theneck at the base thereof b the ta s 5. ln fastening the plate to the necit is placed against the wall thereings6 and 9 in the elastic tabs arepreferably so disposed with relation'to the plate that it is necessaryto stretch the tabs in order to fasten them to the plate7 thus holdingthe plate securely under tension. Elasticity'in the neck contributes tothe forming of an effective watertight closure since the tension in thetabs stretches the neck and brings the walls of the neckv forciblytogether. With regard to opening and closing the neck, the plate ispermanently held in place, there being no necessity of removing 1t. Theremovable function of the tabs 5 is incidental to the function ofholding the plate permanently under tension.

A pair of long elastic rubber tabs 11 'are secured to the neck at the'thick portion between the thinned portions 3 and 4 and a pair of shortelastic rubber tabs 11 are secured to the neck at the thick ortion abovethe thinned portion 3. Theta s 1l are each provided with two holes 6 asshown and the tabs 12 are each provided with one hole 6".

To operate the closure for the bag the section ais folded backwardlyabout the thinned' portion 3 and contacts with the rear face of plate 8than tabs 11 are buttoned thereon, and thereafter the tabs 11 aresuccessively buttoned over the buttons 7, one tab over the other. Theclosure is then complete, the folds a, b, and c of the neck beincompressed together by the action of the e astic tabs which exert atension thereon by reason of the tabs being so designed that they mustbe stretched into engagement with the buttons. Also, as before stated,the neck itself being elastic materially aids in forming the watertightclosure by stretching under tension of the tabs, so that the walls ofthe folded neck are forced tightly together.

The modification shown in Figs. 7 and 8 shows a pocket receiving sectionof elastic material open at its ends and provided with button holes 6 toreceive the studs 7 ofl the metal plate and hold the said plate 8 inposition at the base of the neck.

The compression of the folded neck by the elastic tabs and by its ownelasticity effects a watertight closure.

The bag may be var readily and economically manufactured, t e entire bagand closure being molded simultaneously with one operation, the onlyassembly necessary being the securing of the metal strip stiifeningmember, which serves as the base or foundation against which the foldsare drawn and com ressed by the tension of the elastic tabs.

T e tabs may be formed as extensions of cross bands vulcanized to theneck, these bands being spaced apart to leave the material of the neckproper uncovered as at 3, 4 to thus provide the predetermined lines offold.

Instead of complete tabs being formed integral with the neck of the bagI may provide short extensions 13 Fig. 9 of the cross bands.

These extensions have slots 14 and a removable elastic strap or belt maybe threaded through these slots to answer as tabs, and these may berenewed. I have found, however, that the permanent tabs are durable andwill endure as long as the life of the bag.

Figs. lO and 11 show a further modification of the invention employing aplate 8i1 curved at its ends as at 15 to conform to the neck of the bag.A slot 16 is provided in each of these curved ends 15 to receive therubber tabs 5. The elastic tabs have narrow portions 17 which may passfreely through the slots 16 and wide portions 18 which are wider thanthe slots so as to limit the movement of the tabs therethrough. When itis desired to lill the bag with ice the tabs 5a are unfastened from themetal plate and the plate is pulled away from the neck, the tabsslipping through its slots until stopped by the wide portions 18 of thetabs as shown in Fig. 11. This permits flexing of the neck wall toprovide space for the passage of ice through the neck.

It will be noted (Fig. 6) that when the neck is in folded and closedposition the tabs at pressing the folds in folded position, said itension means connected to and applying its force to the opposite edgesof the neck and in opposite directions transverse to the axis of theneck.
